Step 6: Apply AC Power
NETGEAR GS716T,GS724T,GS748T Series Smart Switch does not have an ON/OFF switch. The method of applying or removing AC power is by connecting or disconnecting the power cord. Before connecting the power cord, select an AC outlet that is not controlled by a wall switch, which can turn off power to the switch. After selecting an appropriate outlet, use the following procedure to apply AC power.
1. Connect the female end of the supplied AC power adapter cable to the power receptacle on the back of the switch.
2. Connect the 3-pronged end of the AC power adapter cable to a grounded 3-pronged AC outlet.
When applying power, the Power LED on the switch’s front panel is Green.
If the Power LED does not go on, check that the power cable is plugged in correctly and that the power source is good. If this does not resolve the problem, refer to Table 5,
Troubleshooting Chart.
Step 7: Manage the Switch using a Web Browser or the Smart Control Center Utility
The NETGEAR GS716T,GS724T,GS748T Series Smart Switch contains software for viewing, changing, and monitoring the way it works. This management software is not required for the switch to work. The ports can be used without using the management software. However, the management software enables the setup of VLAN and Trunking features, and also improves the efficiency of the switch, which results in the improvement of its overall performance as well as the performance of the network.
After powering up the switch for the first time, the Smart Switch can be configured using a Web browser or a utility program called Smart Control Center. For more information about managing the switch, see the GS716T,GS724T,GS748T Series Software Administration Manual on the Smart Switch Resource CD.
Note: When the device powers up, there is a default IP address already configured on the device. The default IP address is 192.168.0.239 and subnet mask 255.255.255.0.

Additional Troubleshooting Suggestions
If the suggestions in Troubleshooting Chart do not resolve the problem, refer to the troubleshooting suggestions in this section.
Network Adapter Cards
Ensure the network adapter cards installed in the computers are in working condition and the software driver has been installed.
Configuration
If problems occur after altering the network configuration, restore the original connections and determine the problem by implementing the new changes, one step at a time. Ensure that cable distances, repeater limits, and other physical aspects of the installation do not exceed the Ethernet limitations.
Switch Integrity
If required, verify the integrity of the switch by resetting the switch. To reset the switch, remove the AC power from the switch and then reapply AC power. If the problem continues, contact NETGEAR technical support. In North America, call 1-888-NETGEAR. If you are outside of North America, please refer to the support information card included with your product.
Auto-Negotiation
The RJ-45 ports negotiate the correct duplex mode and speed if the device at the other end of the link supports auto negotiation. If the device does not support auto negotiation, the switch only determines the speed correctly and the duplex mode defaults to half-duplex.
The gigabit port on the Gigabit module negotiates speed, duplex mode, and flow control, provided that the attached device supports auto-negotiation.
